Thermodynamics at finite strangeness in the holographic model*

A 5-dimensional black hole model has been used to describe the Quark-Gluon Plasma (QGP) over a wide range of temperatures T and baryon chemical potentials µ_B on the QCD phase diagram. In particular this model, constrained to reproduce the lattice QCD thermodynamics at vanishing density, has been employed to compute the QCD equation of state as a function of T and µ_B, and to predict the location of the critical point. The QCD phase diagram is actually 4-dimensional in the thermodynamic variables temperature, baryon number, electric charge and strangeness chemical potentials. In this work, I use the model to explore the phase diagram in the temperature and  strangeness chemical potential plane. I will discuss my results on the phase diagram and equation of state in this plane.
